Description

The rapids plec is an armoured catfish (Loricariidae) from northern South America. The species has a flattened body armoured with bony plates and an inferior sucker mouth. It lives in the strongest jets of rapids, where the bottom consists of large, smooth boulders and the current is very strong; with its sucker mouth it holds on against the flow. With that mouth it rasps algae and growth from the rocks. The stout pectoral fin spines and rough armour can give a puncture wound when handled.
